SPECIFICATION forming part of Letters Patent No. 755,361, dated March 22, 1904.

Application filed September 15, 1903. Serial No. 173,271. (No model.)

To all whom it may concern:

Be it known that LDANIEL E. CoNDoN,a citizen of the United States, and a resident of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Elevator, of which the following is a full, clear, and exact description.

The invention relates to spiral elevators such as shown and described in the Letters Patent of the United States No. 7 19,7 51, granted to me February 3, 1903.

The object of the present invention is to provide a new and improved elevator designed for use in all classes of modern business and industrial buildings in which large crowds of people (and freight, Sac.) have to be carried to, from, and between the various floors in the safest, most expeditious, and systematic manner possible, the elevator being arranged for continuous travel of the cars from one floor to another in the buildmg, at the same t1me enabling the passengers to readily leave or enterj the cars at any floor of the building.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a diagrammatic view of the improvement as applied to a high building, the latter being shown in section. grammatic plan view of the same. a diagrammatic side elevation of the improvement, showing more particularly the arrangement between two floors of the building and a string of connected cars. Fig. 4 is a side elevation of the connection between adjacent cars shown in Fig. 3. Fig. 5 is a cross-section of the improvement at the power-station, showing the propelling mechanism for the train of cars. Fig. 6 is a sectional side elevation of the same on the line6 6 of Fig. 5. Fig. 7 is a plan view of the same, part of the station being shown in section. Fig. 8 is a cross-section of the track in the building and one of the cars having its truck mounted to Fig. 2 is a dia- Fig. 3 is travel on the said track. Fig. 9 is a sectional side elevation of a building provided with an endless elevator having straight flights up and down. Fig. 10 is a sectional plan view of the same on the line 10 10 of Fig. 9. Fig. 11 is a sectional side elevation of a building provided with an endless elevator of modified form, and Fig. 12 is a sectional plan view of the same on the line 12 12 of Fig. 11.

The elevator shown in Figs. 1 to 8, inclusive, is provided with an overhead endless track A, having a spiralup-run A andaspiral down-run A the runs extending in spaced elevator-shafts B and B arranged in a building B, and the said shafts extend through all the floors of the building, as plainly indicated in Fig. l. The shafts B and 13 open at each floor onto a landing B which may be common to both shafts, as indicated in Fig. 2, and the track portions along the landings at each floor are horizontally disposed, as indicated in Fig. 3. The upper ends of the runs A and A" are connected with each other at the top floor or attic of the building by the track-section A and the lower ends of the said runs terminate in a loop A*, extending around a power-station C, which may be located in the basement of the building or outside of the same, if desired. On the track A is mounted to travel an endless train of cars D, each having a truck E, carrying a transverse axle Ffor the truck-wheels Gr, mounted to travel on endless rails H, forming part of the track A, and in the ends of each truck E are arranged vertically-disposed pivot-pins E and E connected by links I with the corresponding pins of the trucks of adjacent cars, so that the several trucks of the whole series are connected with each other to form an endless train of cars D, each of which has a hanger D attached to its top and hung on the axle F of the corresponding car-truck E. On the pins E and E are mounted to turn friction-rollers J and J adapted to be peripherally engaged by the sprockets or arms K and K of a sprocket-wheel K, located in the power-station C and continually rotated by a suitable driving-gear from a motor located in the power-station. This part of the improvement may be the same as described in traveling from one landing to another.

the patent above referred to, so that further detailed description of the same is not deemed necessary, it being, however, understood that when the sprocket-wheel K is rotated in the direction of the arrow (4 then the sprockets K engage the rollers J to impart a traveling motion to the endless train of cars in the direction of the arrows 6, as indicated in Figs. 1 and 2; but when the sprocket-wheel K is rotated in the reverse direction of the arrow (6 then the other sprockets K move in peripheral contact with the rollers J, so as to impart a traveling motion to the endless train of cars in the inverse direction of the arrows b. As shown by the arrows a and Z), the endless train of cars travels up in the shaft B and down in the shaft B but this may be reversed on reversing the rotation of the sprocketwheel K, as above described. cars D arrive at a landing B they travel with their bottoms directly over the landings (see Fig. 3) to allow the passengers to readily step in or out of the cars-that is, the passengers desiring to go from one floor to another one above make use of the cars traveling up and through the shaft B on the run A and passengers desiring to go from a higher floor to a lower floor make use of the cars traveling through the shaft B on the run A In order to support the trucks and cars laterally and guide them along the spiral curvatures during the time they travel on the up and down runs of the tracks, the said runs are provided with a guide-rail L, (see Fig. 8,) on which travel the horizontally-disposed friction-rollers J. If desired, the cars D may be arranged very close together, as illustrated in Figs. 3 and 4, and in this case the opposite sides of adjacent cars are connected with each other by a flexible connection which allows the adjacent cars to assume different levels, especially when The connection referred to preferably consists of a vertically-disposed rod or bar N, supported on the side of one car and engaged by aplurality of friction-rollers N, journaled in bearings N attached to the opposite side of the adjacent car, as will be readily understood by reference to Fig. 4, the friction-rollers N, however, engaging the rod or bar N on the side adjacent to the car supporting the rod. In order to guide the truck-wheels G when a car passes from an inclined track portion or flight to a horizontal floor-landing, and vice Now when the corresponding shaft and also to prevent a person from dropping down the shaft. The support 0 may be a light iron structure in the form of a grille or other open work, but sufficiently strong for the purpose. Each of the shafts B and B is provided with railings P and. P, forming a passage-way for the cars, so as to prevent people from falling out of the cars, it being, however, understood that the outside railings P are open at the landings B for the passengers to readily step in and out of the cars, as will be understood by reference to Fig. 2. Similar railings P and P extend on opposite sides of the cars from the shafts to the power-station, as indicated in the said Fig. 2.

In the arrangement shown in Figs. 9, 10, 11, and 12 the continuous overhead track A has its up-run A and its down-run A extending in straight flights from one floor to the other, and on each floor is a horizontal portion at the landing B of each floor for the ingress and egress of the passengers to and from the cars D, traveling in endless-train fashion on the said track A. The upper ends of the runs A A are connected witheach other by the track-section A and the lower ends of the said runs terminate in the loop A around the power-station 0, shown located in the basement of the building. The detail construction of the elevators shown in Figs. 9, 10, 11, and 12 is the same as above described in reference to Figs. 2 to 8, inclusive, and the difference in the arrangement between the elevators shown in Figs. 9 and 10 and Figs. 11 and 12 consists merely in the fact that the runs of the elevator shown in Figs. 11 and 12 extend in one direction only, while the runs of the elevator illustrated in Figs. 9 and 10 extend in a zigzag line, as will be readily understood by reference to Fig. 9.

It is understood that the endless train (as per Figs. 3 and 4) is run sufiiciently slow, but continuouslysay from sixty to ninety feet per minuteto allow the passengers to readily step into and out of the cars at the landings; but by having the safety-railings described it is evident that passengers are not liable to become injured during their travel from one landing to the other, and in case a car should fall it can only drop to the support 0 immediately below, so that absolute provision is made for the safety of the passengers both in going up in the building or down in thesame.
